AcE'rYLENE-GAS APPARATUS.'

Specification of Letters Patent.

Patented Nov. 21, 1916.

Application led December 11, 1913. Serial N o. 806,041.

T0 all whom t may concern Be it known that I, ALLEN HOPEWELL SEYMOUR, acitizen of the United States, residing at Bainbridge, in the county ofRoss and State of Ohio, have invented certain new and usefulImprovements in Acetvlene-Gras Apgiaratus, of which the following is aspeci cation.

This invention relates to improvements in erator thereby adding to thedisadvantage of after and over-generation.

It is one of the objects of my invention i to provide a generator forsupplying gas to a gasometer, the arrangement being such that arelatively small quantity of carbid may be charged in each separategenerator so that the generator as a whole, will provide for arelatively great gas-producing capacity.

A further and very important object is to completely and wholly insulateeach `separate generator, the one from .the other, so that absolutely nogeneration can be effected in one, during generation in another.

A further object is to provide for a consecutive generation or action ofthe several generators so that when the charge of one has beenexhausted, and the bell of the gasometer descends, generation will beautomatically initiated in the next successive generators. i

Other objects and features of my mvention will be more fully describedin connection with the accompanying drawings and will5be moreparticularly pointed out and ascertained in and by the appended claims.

In the drawings, Figure 1 is a plan viewv of one form of my acetylenegas machine. Fig.v 2 is a sectional view on line 2-2 of Fig. 1. Fig. '3is a sectional view on line 3-3 of Fig. 1. Fig. 4 is a sectional` viewon line 4 4 of Fig. 1.V Fig. 5 is a sectional view on -line 5 5 ofFig. 1. Fig. 6 is a scctional view on line 6-6 of Fig. 1.

In the particular form shown, a gasometer is illustrated comprising atank 1 in which a bell `2 is disposed. `The bellQ may be guided by meansof arms 3 adapted to coact with a guide 4, suitably secured to the tankl, as indicated at 5. The bell 2 is provided with a dome 6 to which asleeve 7 may be secured. The sleeve 7 constitutes a part of a safetyblow-off device, the other part of which consists of a pipe S extendingup into the sleeve 7 so that upon rising movement of the bell 2, to apredetermined height, gas would be discharged through the blow-offdevice when consumption was shut off through the regular supply pipeleading therefrom.

A supply pipe 9 leads from a generator, which will be hereinafterreferred to, and discharges into the upper end of the bell 2, as shown.A consumption pipe 10, leads from the bell to a filter 11, of anysuitable construction, from which a pipe 12 leads to the point of supplyor consumption of the gas.

Next, referring to the generator, 13 designates a main tank having abottom 14 and provided with a centrally disposed upwardly extendinghollow shaft 15 forming a gas-receiving chamber which communicates withall of the generators through a water seal. The gas-receiving chamber 15is closed by a bell 16 which may be anchored against upward movement inany desirable manner and which projects downwardly into the watercontained in the tank 13 so as to seal the chamber 15 against egress ofgas except through the supply pipe 9. As will be seen by reference toFig. 3, the supplyI pipe 9 opens to the gas-receiving chamber near theupper portion thereof.

The main tank 13 is shown supported in a sealing tank 17, in a manner todispose the bottom 14 of the main tank at some distance above the bottomof the sealing tank, and as shown, I have provided the main tanklB withextensions 18 for supporting the main tank. A water level 19 ismaintained in the sealing tank at an elevation controllable by an outlet20, and such level is preferably restricted so that it will not closethe lower opening of the receiving chamber 15, which opening isindicated at 21. The

space indicated at 22, forms a gas space from which the gas ascends intothe chamber 15 from delivery means leading from the several generators,in a manner which will here-v inafter morel fully appear'. The chamberformed bythe sealing tank and the bottom of the main tank, is itselfsealed by a liquid level 23, between the main tank and the sealing tank,which level is .maintained by gas pressure against level 19. A suitablesupport 24 may be provided for the sealing tank 17. l

A plurality of carbid holders generally indicated at 25a to 30, aredisposed in the main tank 13, and as all are of similar constructiononly one need be described in detail. Inasmuch as the tank is showncircular, the carbid holders are disposed circumferentially about thereceiving chamber 15.

Referring to holder 25a, the same consists of a receptacle having anupstanding tube 26 therein which extends toward but not to the top ofthe holder or receptacle. The holder 25@L will be immersed in the liquidin the tank 13, as shown in Fig. 3, so that the upstanding tube 26 willincrease the area of the holder which is subjected to the water therebymaintaining. a comparatively low temperature in the holder'notwithstanding the heat generated by the action of water on the carbidin generating gas. The top of the tube 26 is closed by a supporting cap27 provided with openings therein through which nozzles 2S and 29project. The nozzles 28 and 29 are tapered so that they will fit tightlyin the cap-support 27 and thereby support the carbid holder in theposition shown. Nozzle 2S is mounted upon a water inlet pipe 30 andnozzle 29 is mounted upon a water overflow pipe 31. Each carbid holderis pro` vided with a water inlet and an overfiow pipe connected in themanner shown in Fig. 4. The inlet or supply to the pipe 31 is indicatedat 32 and the final outlet at 33. The path of the pipe 32 is clearlyindicated in Fig. 1 and adjacent each holder, a pipe coupling 34 will beprovided for connection of pipes 30 and 31 so as to force the water from32 up through 30 and into the holder and then out through pipe 31 fromthe holder to the next generator. The pipe coupling 34 has two outletsat one side thereof to permit connection of the pipes 30 and 31, and apartition is disposed across the interior of the coupling to precludecommunication between the two side openings thereof. At the start orfirst installation, pipe 32 will be primed, past the couplings 34, so asto prevent any of the gases generated in the first holder to beoperated, from passing through the overflow 31 oi' such holder into thereserved charge of the next holder.

Each holder is provided with Va valve4 limited romupward movement b vreason of gas pressure in the holder, by a lift bar 36. The lift bars,or closingV levers, which have for the several holders been designated36, 42, 43, 44, 45, and 4G are pivotally mounted and are made to havesuflricient weight that they will normally hold the covers 35 closed torest against the upper rim edges of the various holders and to thusestablish the desired closure of the holders. A suitable abutment 37 mayserve to prevent upward movement of the bell cover 35 beyond aVpredetermined extent. However, in the present form, the bell, cover 35will be raised by pressure of gas in the holder 25 sufficiently topermit of passage ofl the gas out of the holder 25. Each holder isprovided with a gas discharge pipe, the discharge pipe of holder 252Lbeing indicated at 38, and the same extends upwardly in the bell cover35 to a pointnear the top of the holder 25a. Said discharge pipe 3Sextends downwardly through the bottom 14 of the main tank to a pointbelow the sealing level 19 of the sealing tank 17 VThus the gasdischarge from pipe 38 will bubble up through the sealing water and willflow into the gas space 22 and rise in the receiving chamber 15. Fromthe receiving chamber 15 the gas will find an outlet through the supplypipe 9 leading to the gasometer. In order to provide supports for thepiping and guiding devices for the bell covers, I provide upper andlower partitions 39 and 40 which serve to take the place of frame work.The closing levers 36, 42, 43, 44, and 46 may be secured to the upperpartition 39. in any desirable manner, and they may be hinged at 41, asshown. In Fig. l; the closing or retaining levers are indicated at 36,42= 43,

44, 45 and 46. At the right of Fig. 3., the

holder 28a is provided with an upright spout 47 and a discharge pipe 48leading from the bell cover' 49 to a 4point below the liquid level 19 inthe sealing chamber. Y

I provide means controlled by the bell of the gasometer for governingthe supply of water to pipe 32, and as shown in Fig. 6, the pipe 32terminates in a funnel 50 into which a pet-cock 51 discharges. Thepetcock 51 is attached to a valve seat outlet leading from an auxiliarytank 53. Said auxiliary tank 53 is connected at 54 so as to be suppliedfrom water in the tank 1 of the gasometer. A valve 55, provided with astem 56, slidable in guides 57, is connected with an operating lever 58.The operating lever 53 is pivotally mounted at 59 on a support GO andone end of the lever is connected by a chain 61 to the valve stem 56 ofthe other endY by chain 62,v to the bell 2. rhus whenthe bell 2 of thegasometer rises under a supply of `gas through supply pipe 9, the valvewill be moved toward a closing po-V sition, and when consumption or lackof supply of gas causes the bell 2 to descend, the

valve Will rise, as shown in F ig. 6. The pet-cock 5l is to govern theflow from the auxiliary tank 53 to the pipe 32.

In vieu'v of the foregoing description, and by reference to Fig. l, itWill be seen that the carbid holders 25a to 30a, or generators as theymay be called, are serially connected so that Water supply to the firstholder or generator25 will completely exhaust the charge thereof Withoutin any Way affecting the charges of carbid in the other generators. ItWill be further clear that Water will be continuously supplied to thefirst generator until the charge has become exhausted and when the levelin the first generator reaches the nozzle 29 of its overflow pipe 31,the AWater supply to the lirst generator or holder 25 will pass through'overflowr pipe 3l to pipe 32 and therefrom into generator 26a, or theholder thereof. By having the pipe 32 initially filled so that the steamand gases generated in the iirst holder could not direotly pass throughpipe 3l into the next holder, it Will be seen that each holder isisolated from its companion holder so that only a serial operation ofthe generators Would be possible. W'hen the carbid of all of thechambers has been exhausted, then it will be necessary to clean out thesame and the bell covers thereof can be readily removed, and likewisethe holders themselves, for this purpose. I-Iowever, should the chargesof the several generators become exhausted at night time, any one couldbe recharged Without in any Way affecting the others.

From the foregoing it Will be seen that I have provided an apparatus inWhich the holders are not only surrounded by Water which will absorb theheat used in generation, but also the charge in each of the holders isprotected from the action of Water vapor and gas, Which protection isafforded by the device of my invention, both as regards each individualgenerator, and as regards the Working generator with respect to thegenerator which has not been started. It is one of the special featuresof my invention that Whereas I provide a plurality of generators Whichcan all be charged at once and operated serially, I totally isolate eachgenerator from its companion generators by a Water seal so that therecan be no surplus generation over and above the generation in theWorking chamber. Furthermore, there can be no after generation by reasonof the fact that the charge in one chamber is exhausted, Where suchchamber is the Working chamber, prior to starting a new generator.

It is believed that the device of my invention will be clear from theforegoing disclosure and While I have herein shown and described onespecific form of my invention, I do not Wish to be limited theretoexcept for such limitations as the claims may import.
